15.5 Assembly of the Rotor
WARNING
The rotor is magnetic! Risk of injury and
crimping danger by magnetic forces!
⇒ Eliminate movable metal objects or secure them
against movement.
⇒ Carefully handle magnetic parts.
⇒ Wear protective clothing and use mounting tools.
The rotor is guided into the rotor hole on a spacer sleeve using two
insertion fittings and attached to a clamp plate. Then it must be guided –
so that it is centered – over the shaft to be driven in the stator and
fastened using a clamp collar.
During installation, note the information in the dimension sheets Figs. 15-
2 and 15-7
• The number and type of fastening holes
• the minimum depth of thread and tightening torque.
Note:
• The necessary screw length depends on the machine
construction.
• The screwed connections must be able to take up both the
force due to the weight of the motor and the forces acting
during operation.
Attend to cleanliness during all working steps!
Heed the notes regarding the preparation of assembly in section 11.3
“Mechanical Installation“.
1. Connect the rotor, together with the spacer sleeve, to a clamp plate.
After attachment is complete, it must be ensured that both centering
diameters of the rotor hole have been guided onto the spacer sleeve.
(see Fig. 15-2)
2. Connect the rotor using a mounting tool to insert the rotor into the
stator (see Fig. 15-8 ).
3. Using the mounting tool, push the rotor over the shaft end up to the
end position. We recommend you to consider using a slide bearing
(gunmetal bush, etc.) on one side of the shaft end, which allows axial
length compensation due to the somewhat stronger heating of the
rotor compared to the shaft during motor operation. (see Fig. 15-7)
WARNING
Injuries/damage due to strong magnetic forces!
⇒ Due to the permanent magnets on the rotor and the
resulting magnetic forces, the rotor is suddenly
pulled into the stator. Use suitable assembly tools.
4. Use a clamp collar to attach the spacer sleeve to the shaft end. The
clamp collar provides the safe transmission of force from the motor to
the shaft to be driven.
